The proposed devices can be used as power splitters or combiners and are based on lithium niobate on insulator (LNOI) technology, a promising emerging platform for the realization of integrated optical devices. We consider 1(times)N MMI splitters and N(times)1 combiners, with N being the number of output/input ports. We define the design and the optimization criteria to achieve the best performances in terms of insertion loss and output power uniformity over a large wavelength range (i.e., from 1500 to 1600 nm). In particular, we investigate seven configurations of MMI couplers with N ranging from 2 to 8. The insertion loss for all the designed MMI couplers with N ranging from 2 to 8 varies from 0.018 to 0.41 dB, while the uniformity for all MMI splitters ranges from 0.020 to 0.335 dB across the considered wavelength range. The impact of the amplitude and phase errors on the transmittance of MMI combiners with N ranging from 2 to 8 input ports shows that the transmittance variation is less than 1.5 (%), indicating high robustness and reliable performance in various photonic applications. We compare our MMI couplers results with those of the state-of-the-art based on different material platforms, including LNOI, obtaining much lower insertion losses.</div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 3","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11082-025-08060-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the propagation dynamics of vortex Hermite-Gaussian (VHG) beams in parabolic potential wells, introducing two key parameters: off-axis displacement and chirp to represent the beam’s initial displacement and angle. Findings indicate that low-order VHG beams can form stable solitons. Joint adjustments of off-axis displacement and chirp enable precise control over soliton trajectories, enabling propagation along elliptical or circular helical paths. The rotational dynamics of these helical paths interact with the vortex of the beams, resulting in modifications to the optical field structure. Interestingly, by adjusting soliton trajectories and vortex characteristics within soliton arrays, novel optical field structures emerge during the arrays’ expansion or contraction. These structures periodically alternate with the arrays while exhibiting rotational dynamics, demonstrating the intricate interplay between the solitons and their collective behavior. These findings present promising applications in optical information encoding. The bidirectional control over soliton trajectories and vortex characteristics offers a versatile approach for manipulating optical fields, opening new possibilities for advanced light-field customization.</div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 3","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, using a polarization control structure allows for spurious suppression and encoded signal loading. The system can generate various signal formats, including rectangular optical frequency combs, frequency-multiplied signals, dual-frequency encoded signals, and multiple pulse waveforms. Simulation results demonstrate the successful generation of 16 GHz frequency-doubled signal and 32 GHz frequency-quadrupled signal, with spurious suppression ratios of 37.9 dB and 44.8 dB, respectively. It can also generate four-line rectangular optical frequency combs with frequency multiplication factors of 2 and 4, achieving flatness values of 0.24 dB and 0.16 dB. Furthermore, the system can generate symmetric triangular pulses and Sinc-Nyquist pulses with adjustable repetition frequencies, as well as encoded signals with good pulse compression performance, having PCR values close to the theoretical value of 13.
